WILLIS W. WOODRUFF, OF MINNEAPOLIS, MINNESOTA.

RAILWAY-RAIL TIE.

Application fi1ed March 21, 1914.

To all whom it may concern Be it known that I, WILLIS W. WOODRUFF, citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Railway-Rail Ties, of which the following is a specification.

This invention relates to improvements in railway ties, and has for one of its objects to construct a railway tie combining a cement or concrete core and an inclosing metal shell so arranged that the concrete core and the metal shell mutually support and sup- 5 plement each other.

Another object of the invention is to provide a combined concrete and metal tie with an improved means for supporting the railway rails upon the tie.

With these and other objects in view the invention consists in certain novel features of construction as hereinafter shown and described and then specifically pointed out in the claims; and in the drawings illustrative of the preferred embodiment of the invention Figure 1 is a plan view of one of the improved devices including the rail fastening portion. Fig. 2 is a side elevation partly in section on the line 2-2 of Fig. 1.

Fig. 3 is a transverse section of one of the improved ties in section on the line 3-3 of Fig. 1.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The improved device comprises a shell formed from a relatively heavy plate of metal bent into a novel shape transversely to and with a core of cementitious material, preferably concrete. The metal shell is formed with a curved upper portion, as shown at 10, and'with diverging or flanged portions at the bottom and side walls beat tween the curved portions 10 and 11 directed inwardly, as represented at 12. The flanges 11 project for a considerable distance beyond the side lines of the body 10 of the tie so that a relatively wide base is produced, as represented more clearly in Fig.

3. The shell is provided with a core of cementitious material, preferably concrete, and represented conventionally at 13. The lower line of the core is even with the lower line of the flanged portions 11 whereby the core is provided with a correspondingly Specification of Letters Patent.

wide base to firmly support the tie, and effectually prevent all tendency to overturn, while at the same time the height is not de creased, consequently the full strength is retained vertically. By forming the shell with the inwardly directed portions 12 the required quantity of cement is reduced without reducing the strength of the structure.

Bearing upon the upper curved portion 10 of the shell are rail supporting blocks 14:, the upper faces of the blocks having transverse recesses 15 to receive the rails represented conventionally at 16, and with the lower faces of the blocks curved to correspond to and closely engage the curved portion 10 of the shell of the tie. The blocks 14 are secured to the shell by bolts or like devices 17, the bolts having heads 18 within the shell of the tie and surrounded by the cementitious material. Rail engaging clips 19 are secured to the blocks 1d by clamp bolts 20. Any required number of the bolts 18 and clips 19 may be employed, but generally two bolts at each end of the block and two clips for each block will generally be used, as represented in Fig. l.

The blocks 14 may be of any suitable substance or material, and may be of wood, some forms of rubber compounds or the like, so that the blocks will yield slightly with the impact of the rolling stock.

The improved device is simple in construction, is not affected by climatic condi tions and is practically indestructible.

Reinforcing rods or like members 21 of steel or other metal may be inserted within the cementitious core of the tie to increase the strength.

Having thus described the invention, what is claimed as new is:

1. A device of the character described comprising a metal shell open at one side and laterally enlarged at the open side with portions of the side walls of the shell directed inwardly, whereby a shell having a constantly flaring open lower side and 0011- tracted intermediate portions is provided, and a filling of cementitious material for said shell, one face of the cementitious material extending from side to side of the outwardly flaring side walls of the shell at the open side thereof.

2. A railway tie comprising a metal shell having a curved upper portion and oppositelv directed diverging lower portions extending beyond the upper portion whereby copies of this patent may be obtained for a relatively wide bearing base is produced, the sides of the shell being directed inwardly between the upper portion and the lower diverging portions, a rail support having a hollow lower face conforming to and engaging the curved upper portion of the shell, holding members passing through the shell and the rail support and including heads within the shell, anda core of cementitious material filling the shell and in which the heads of the holding members of the rail supports are embedded.

3. A device of the character described comprising a metal shell open at one side and laterally enlarged at the open side with portions of the side walls of the shell directed inwardly, whereby a shell having a constantly fiarlng open lower side and contracted intermediate portions is provided, a

filling of cementitious material for said shell. 20
